EFB Elektronik Stewart SS37 RJ45 Male Field Assembly Connector, Shielded, Tool-free, Cat.6A/7/7A/8, Zinc Die-Cast, Gold Contacts

For high-performance Ethernet links where speed and on-site simplicity cannot be compromised, the Stewart SS37 from EFB Elektronik eliminates the usual trade-off. This shielded RJ45 plug terminates without any crimping tool, yet supports up to 40 Gbit/s across Cat.6A to Cat.8.2 cabling. A zinc die-cast housing and 50µ" gold-plated contacts deliver durability and signal integrity in demanding industrial or enterprise environments.

Highlights

• Supports Category 6A, 7, 7A, 8.1, and 8.2 networks for future-proof performance.
• Tool-free IDC termination: no crimping tools required, ideal for on-site assembly.
• Shielded 8P8C design with 50µ" gold plating for reliable, corrosion-resistant connections.
• Accepts both solid and stranded conductors from AWG 22 to 26, with cable diameters 5.0–9.0 mm.
• Reusable up to 10 cycles, reducing waste and total cost of ownership.

In daily use

The SS37 excels in scenarios where downtime is costly and precision matters. Field technicians can terminate cables in seconds without specialized tools, even in tight spaces. The robust zinc die-cast body withstands harsh conditions, while the wide operating temperature range (-40°C to +85°C) suits outdoor or industrial deployments. PoE support up to 4PPoE (IEEE 802.3bt) means it can power devices like cameras or access points directly through the connector.
